Sometimes, bones are the only accessible source of DNA, thanks to their structure, which preserves DNA comparatively well and for a long time. The main problems of DNA extraction from bones are DNA degradation due to environmental factors and the presence of soil-derived inhibitors like humus acids [1â10].
DNA is a small segment of the chromosome that codes for a specific trait.DNA is found in the nucleus of cells.hence a DNA sample can be obtained from the blood, skin and even hair.but bear in mind that DNA cannot be obtained from red blood cells as they do not have a nucleus. and T and C and G fit together, and they form a ladder-like double helix shape. Each of these combinations instructs a single amino acid (small unit of protien) to do a certain job, whether it is A and T, T and A, C and G or G and C. Each person has a unique DNA and so do all animals etc.
